Shell grit samples from the Mediterranean coast of Israel have been examined, containing five Cardiidae species. Parvicardium trapezium is here reported for the first time from Israel and Afrocardium richardi for the second time. The genus Afrocardium is discussed. A. richardi exhibits large variation in shape, outline and coloration, but has a rather uniform rib number and rib sculpture. The same applies to its congeners, most of which the present status is doubtful. Its suggested life habit, i.e. byssally attached to a substratum, might be an explanation for this variability. However, this assumption has to be confirmed by the examination of living populations. Information is given about abberations and the maximum size of A. richardi.
